Abstract
A retractable leash system includes a housing, a leash, a spool, and a brake. The spool is attached to the leash and disposed within the housing. The leash is configured to be rotationally biased so as to urge the leash into a spooled configuration. The brake includes an operating button, a compression spring, and a brake member coupled to the operating button. The brake member is associated with the compression spring and is configured to engage the spool by operation of the operating button, such that, when the brake is engaged, the spool is prevented from rotating in an unspooling direction and capable of rotating in a spooling direction.

A retractable leash system comprising:
- a housing;
- a leash;
- a spool attached to the leash and disposed within the housing, the leash being configured to be rotationally biased so as to urge the leash into a spooled configuration;
- and
- a brake including an operating button, a compression spring, and a brake member coupled to the operating button, the brake member being associated with the compression spring and configured to engage the spool by operation of the operating button, such that, when the brake is engaged, the spool is prevented from rotating in an unspooling direction and capable of rotating in a spooling direction.
A retractable leash comprising:
- a housing;
- a spool disposed within the housing, the spool including a braking notch, a clearance area, and a cam surface;
- a leash attached to the spool, the spool being rotationally biased to wind the leash upon the spool;
- and
- a brake including an operating button and a brake member coupled to the operating button, the brake member configured to engage the spool by operation of the operating button, such that, when the brake is engaged, the spool is prevented from rotating in an unspooling direction and capable of rotating in a spooling direction, the brake, when activated, urging the brake member into the clearance area, the brake member configured to engage the braking notch when the spool is rotated in an unwinding direction, and to engage the cam surface when the spool is rotated in a winding direction.
